My personal opinion is why bother. The first 5 years I was in the ME I paid a grand total of 0 to the federal government. Now I pay around 10% tax on my gross wages. I can live with that. It's a heck of a lot better than when I was in the USA.
At least you know that your contribution will provide you with an excellent social/medical security should you have to leave the UAE prematurely.
